Description

Technical Field

[0001] The utility model relates to the technical field of evaporator defrosting, in particular to an evaporator vibration defrosting mechanism. Background Technique

[0002] An evaporator is an object that converts a liquid substance into a gas. There are a large number of evaporators in industry. Among them, the evaporator used in the refrigeration system is one of them. During the operation of the evaporator, especially in a low-temperature and high-humidity environment, its surface is prone to frosting. The formation of the frost layer will not only affect air circulation, increase the heat transfer resistance between the air and the evaporator, reduce the heat transfer efficiency, but also increase energy consumption and even affect the normal operation of the refrigeration system. Therefore, timely and effectively removing the frost layer on the surface of the evaporator is crucial for maintaining the stability and efficiency of the refrigeration system.

[0003] In the existing evaporators, there is still a problem of poor defrosting efficiency during actual use, and the frost cannot be completely removed, which will affect the actual operation and use of the equipment and is not conducive to the more efficient use of the evaporator in practice.

[0004] Therefore, the utility model provides an evaporator vibration defrosting mechanism. Content of the Utility Model

[0006] The utility model provides the following technical scheme: an evaporator vibration defrosting mechanism, including a frame, vibration motors are arranged on both sides of the frame, a wire mesh is fixedly connected to the output shaft of the vibration motor, and refrigerant pipes are arranged on both sides of the frame.

[0007] Preferably, moving wheels are arranged at the bottom of the frame, and the positions of the moving wheels are distributed on both sides of the bottom of the frame.

[0008] Preferably, a connecting pipe is arranged inside the frame, and the outer surface of the connecting pipe penetrates through the inside of the frame.

[0009] Preferably, springs are fixedly installed on the upper surface of the frame, and spring limit posts are fixedly installed on the upper surface of the frame.

[0010] Preferably, a bolt is threadedly connected to the outer surface of the spring limit post, and the upper surface of the bolt abuts against the bottom of the frame.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The vibration defrosting mechanism of this evaporator, through the use of a vibration motor, a wire mesh, a refrigerant pipe, and a connecting pipe, combined with the action of the external air flow direction, can perform a more comprehensive defrosting operation on the surface of the evaporator. Through the use of moving wheels, springs, spring limit posts, and bolts, the vibration motor and the wire mesh can be fixed and supported, while limiting the vibration amplitude to prevent equipment damage and improve the defrosting effect. Thus, the problem of how to defrost efficiently is solved, achieving a more thorough defrosting effect and avoiding the impact on the equipment during defrosting, which is beneficial for the overall more efficient use in practice and convenient for its popularization and application.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figure 1 , Figure 2 and Figure 3 , the vibration defrosting mechanism of the evaporator includes a frame 1. Vibration motors 2 are arranged on both sides of the frame 1. The output shaft of the vibration motor 2 is fixedly connected to a wire mesh 3. Refrigerant pipes 8 are arranged on both sides of the frame 1. Moving wheels 4 are arranged at the bottom of the frame 1, and the positions of the moving wheels 4 are distributed at both sides of the bottom of the frame 1. A connecting pipe 9 is arranged inside the frame 1, and the outer surface of the connecting pipe 9 penetrates through the inside of the frame 1. A spring 5 is fixedly installed on the upper surface of the frame 1. A spring limit post 6 is fixedly installed on the upper surface of the frame 1. A bolt 7 is threadedly connected to the outer surface of the spring limit post 6, and the upper surface of the bolt 7 abuts against the bottom of the frame 1.

[0019] Specifically, by using the vibration motor 2 as the power source of the system, vibration is generated through electric drive. It generally includes a motor and a vibration device. When the motor, such as a three-phase asynchronous motor, rotates, the rotational motion is transmitted to the vibration device through a coupling or direct connection. The vibration device then converts the rotational motion into linear or rotational mechanical vibration. By using the wire mesh 3, which covers the surface of the evaporator, its structure helps the separation of the frost layer from the evaporator surface and also serves as a transmission medium for the vibration force. The moving wheels 4 installed at the bottom of the frame 1 enable the entire device to have good mobility and flexibility, facilitating rapid transfer and positioning in different working areas, improving work efficiency and the adaptability of the device. The connecting pipe 9 installed inside the frame 1 not only provides necessary structural support for the device but also ensures the air circulation or liquid circulation inside the device, contributing to maintaining the normal operating state of the device. In addition, the springs 5 and spring limit posts 6 fixedly installed on the upper surface of the frame 1, and the bolts 7 threadedly connected to the outer surface of the spring limit posts 6 together constitute an adjustable shock-absorbing system. This design can effectively absorb the vibration energy generated by the vibration motor 2, reduce the vibration and noise during the operation of the device, protect the device structure from damage, and at the same time improve the stability and service life of the device. By adjusting the tightening degree of the bolts 7, the shock-absorbing effect can be flexibly controlled to adapt to different working requirements and environmental conditions.

[0020] Working principle: During use, when the frost layer on the evaporator surface accumulates to a certain extent and affects the refrigeration efficiency, the vibration motor 2 is started. The vibration motor 2 begins to rotate and converts the rotational motion into linear or rotational vibration through the built-in mechanism. The vibration energy of the vibration motor 2 is evenly transmitted to the evaporator surface through the wire mesh 3. The wire mesh 3 not only increases the vibration area but also promotes the separation of the frost layer from the evaporator surface through its unique structure. Under the continuous vibration action, the frost layer on the evaporator surface is subjected to periodic impact forces, resulting in a gradual weakening of its bonding force with the evaporator surface. At the same time, the structure of the wire mesh 3 further promotes the loosening and shedding of the frost layer. Finally, the frost layer falls off from the evaporator surface under the combined action of gravity and vibration force. During the entire defrosting process, the refrigerant pipe 8 continues to circulate the refrigerant to maintain the operation of the refrigeration system, and the connecting pipe 9 ensures the smooth flow of the refrigerant between the evaporator and other parts of the refrigeration system. The springs 5 and spring limit posts 6 play a buffering and limiting role during the vibration process to prevent excessive vibration from damaging the device. At the same time, the stable structure of the frame 1 also ensures the stability of the entire system. In addition, the external airflow is guided to the evaporator surface through the wire mesh 3. The airflow forms a thin air film on the evaporator surface, which helps the rapid melting and shedding of the frost layer. At the same time, the airflow can also carry away the melted frost water to prevent it from refreezing.
